Kimmo Huosionmaa Above the text is a mushroom-shaped cloud, what has been formed by the warm gas bubble, what has been raised from the water. The formation process of this cloud is similar to nuclear explosions. But temperature is lower. Normally nuclear explosives would be noticed by increasing level of radiation. And that would uncover the atmospheric nuclear tests. The nuclear test is prohibited in the atmosphere, undersea an Earth orbiter. The latest fusion weapons are problematic because they would not leave radioactive fallout behind them. Ignition process of those fusion devices would happen by heating lithium pieces by using high-power laser rays. The laser would raise the temperature high enough for starting fusion reaction in the piece of lithium. Those weapons are so clean, that they would not uncover by the radioactive fallout. The ignition of that system would happen by using carbon monoxide laser, what would power by acetylene light. Those systems are extremely ...
